This man can perform an almost impossible bar trick with nothing more than an empty crisp packet.<br /><br />A customer at the Upstairs Downstairs bar in Londonderry, Northern Ireland, is faced with the ultimate of pub dilemmas – an upside-down pint.<br /><br />But the skilled patron doesn't let this faze him.<br /><br />He opens up a crisp packet and flattens it out. <br /><br />Using a steady hand, he slides the pint of Guinness onto the crisp packet and folds it up around the glass. <br /><br />"Take your time," his friends tell him before he inverts the stout. <br /><br />Amazingly, not a drop was spilt. <br /><br />The stunned barman said he had "seen it all".<br /><br />The clip was filmed on October 11.
